Julia Hartz, co-founder and CEO of Eventbrite, wanted to re-imagine ticket sales.
"The idea was really to democratize ticketing," Hartz told CNBC. "We wanted to harness the power of technology to make it possible for anyone to sell tickets to any type of event."
Since it was founded in 2006, Eventbrite has become one of the largest self-service ticketing platforms. In 2015, the company sold 2.1 million tickets, and it expects "significant growth" for this year.
But it was not an easy path to success.
